  Solution Architecture
  Module Selection: Miniature surface-mount PIR modules (e.g., HC-SR501) with size <20mm×20mm for integration into embedded lighting (ceiling lights, corridor lamps).
  Linkage Logic: Connect to MCUs (e.g., ESP32) via GPIO for "person detected - full brightness; person present - dimmed; person leaves - 30s delay off" control. Integrate light sensors (e.g., BH1750) for daytime auto-shutdown.
  Energy Savings: Reduces lighting energy consumption by 30%-50% compared to traditional switches, ideal for corridors and bathrooms.

  Typical Scenarios Smart Homes: Integrates with Alexa/Mijia systems, allowing APP-adjustable sensing distance and delays. Commercial Lighting: Mall corridors use zoned sensing via RS485 bus for collaborative multi-module control.

  III. Optimization of Sensing Solutions for Security Systems

  Enhanced Intrusion Detection Design Anti-Interference Technology: Dual-element complementary sensors suppress ambient temperature interference; pulse counting (2 consecutive pulses trigger alarm) reduces false positives. Multi-Dimensional Linkage: Combines with microwave radar modules (e.g., HB100) for "infrared + microwave" dual detection, triggering alarms only when both activate to avoid curtain sway or insect interference. Concealed Installation: Modules with integrated lens-housing designs (e.g., RE200B) hide within ceilings or decor for covert security. Data Transmission and Response Wireless Transmission: LoRa modules (e.g., EBYTE E32-433T30D) enable low-power long-range (3km open area) data upload, suitable for villa/factory perimeter security. Rapid Response: <0.5s trigger delay, with local buzzer alerts and cloud notifications (via NB-IoT) within <3s.

  IV. Selection and Deployment Considerations

  Environmental Adaptation Avoid direct exposure to air vents/heating sources. Install at 2.2-2.8m (indoor) or 3-5m (outdoor) height, tilted 15°-30° to cover human activity zones. Outdoor use requires IP65 waterproof modules (e.g., AM312-IP67) with sunshades to minimize solar interference. Cost-Reliability Balance Consumer scenarios: HC-SR501 (~$2/unit); industrial use: Prioritize stability (e.g., Panasonic EKMC1603111, temp drift <±2%/℃). Batch deployment: Reserve 10% redundant modules with self-diagnostic voltage checks for fault

  Signal Hunt: An ESP-NOW Workshop & Treasure Hunt

  Hello everyone! We’re planning on organizing a two-phase event that explores device-to-device communication using ESP-NOW protocol :

  Workshop: Participants learn to build and program ESP32-based receivers with a web interface that directly exchange signal data using ESP-NOW for RSSI-based distance approximation.

  Signal Hunt Competition: Equipped with these receivers, participants will track hidden ESP32 transmitters scattered around the campus, each with distinct point values.

  Current hardware setup:
  Reciever(one per team):
  Esp32 ~ 360rs
  9v battery = 20rs
  9v battery clip= 5rs
  buck converter (MP1584 or LM2596) ~ 45rs
  Perfboard + male to female berg strip ~30rs
  Total per reciever ~ 460rs
  Transmitters :6
  Components same as recievers = 460*6~2760rs

  (using non-rechargeable batteries to reduce cost,
  will using a 7805 voltage regulator IC be a viable way to reduce cost further?)

  We’d love your suggestions on ways to simplify hardware, reducing the cost, secure partnerships and funding, or enhance the interactive elements. Thank you, looking forward to any ideas that can help make the event engaging and successful!

  @mahesh02 From the current Arduino ESP32 board files, we don't need to install the ESP-NN separately.

  But try to choose the esp32 board version 3.1.3 and check, as I also faced issues with the latest esp32 board file.

  @borncurious Hi, The best method is to use a motor driver like L293D and give power externally.

  The reason I wanna use online tools only is because, I have been using my company's lappy and I am restricted to install any other Softwares. So, online tools will be an easy way for me. by the way I have found another way too. EasyEDA provides an super easy solution for creating custom PCB shapes. It really came in handy for me.

  @salmanfaris I mainly did this project by following two tutorials in youtube its link is mentioned in my channel.Basically it runs with the help of visual studio code and pycharm.Pycharm is used to detect the hand movement and with the helpm of autopy we move the mouse.By serial port cmmunication we can send the x,ycoordinates in to the arduino and move the servo
